Abstract
The utility model relates to the field of engineering motors and especially to a motor flywheel fixing mechanism. The motor flywheel fixing mechanism comprises a flywheel and a motor shaft, a flywheel mounting hole passes through the motor shaft, a blind hole with the diameter larger than that of a center hole is opened at the center hole of the flywheel, the blind hole and the center hole are concentric, a stepped hole is formed inside the center hole of the flywheel, and an expansion sleeve of an appropriate size is arranged in an annular groove formed by the stepped hole and the motor shaft. According to the motor flywheel fixing mechanism provided by the utility model, the expansion sleeve and the annular groove are used to fix the flywheel, the motor flywheel fixing mechanism is simple in structure and easy to disassemble, the fixation of the flywheel is safe and reliable, and the processing cost is low.
Description
Technical field
The utility model relates to the engineering electric motors, especially a kind of motor flywheels fixed mechanism.
Background technology
The Main Function of motor flywheels is the moment of inertia that increases motor, at run duration, reduces the impact damage to whole system, guarantees the even running of motor.In order to increase the moment of inertia of flywheel, it is larger that the outside dimension of part flywheel is done, and weight is very heavy, and how fixing and can easily install and remove flywheel is the problem that design of electrical motor and workshop assembling must be considered and solve.Adopt securing member to connect or the conventional fixing meanss such as hot jacket interference have weak point, such as assembling and dissembling process is comparatively complicated, inconvenient user's on-site maintenance, and motor shaft is higher with flywheel cooperation place processing request, design and process all more loaded down with trivial details.
The utility model content
Goal of the invention of the present utility model is to overcome the defect that prior art exists, thereby realizes the motor flywheels fixed mechanism.
For achieving the above object, the technical solution of the utility model is: a kind of motor flywheels fixed mechanism, comprise flywheel and motor shaft, described flywheel installing hole is through motor shaft, described flywheel central hole has the blind hole that a diameter is greater than centre bore, described blind hole is concentric with centre bore, at the inner stepped hole that forms of flywheel centre bore, is provided with the expansion set that size is suitable in the cannelure that described stepped hole and motor shaft form.
Because expansion set is standard component, the requirements such as concrete type selecting, calculating, installing/dismounting can be with reference to JB/T7934-1999 " bulging joining sleeve pattern and basic size ", can adjust as requested and select suitable flywheel form during use, and then the fit dimension of definite axle, to meet specific instructions for use.
The beneficial effects of the utility model:
1. motor flywheels fixed mechanism of the present utility model, simple in structure, easily realizes, processing cost is lower.
2. motor flywheels fixed mechanism of the present utility model adopts fixedly flywheel of expansion set and cannelure, and dismounting is than being easier to, and flywheel is fixing safe and reliable.
The accompanying drawing explanation
Fig. 1 is the structural representation of motor flywheels fixed mechanism.
Embodiment
Also by specific embodiment motor flywheels fixed mechanism of the present utility model is done to more detailed description below in conjunction with accompanying drawing.
Embodiment:
Referring to Fig. 1: 1-motor shaft, 2-expansion set, 3-flywheel.
Motor flywheels fixed mechanism of the present utility model comprises flywheel 3 and motor shaft 1, described flywheel 3 installing holes are through motor shaft 1, described flywheel 3 central hole have the blind hole that a diameter is greater than centre bore, described blind hole is concentric with centre bore, at the inner stepped hole that forms of flywheel 3 centre bores, in the cannelure that described stepped hole and motor shaft 1 form, be provided with the expansion set 2 that size is suitable.
The specification of described expansion set 2 adopts JB/T7934-1999.
Claims (2)
1. a motor flywheels fixed mechanism, comprise flywheel and motor shaft, described flywheel installing hole is through motor shaft, it is characterized in that: described flywheel central hole has the blind hole that a diameter is greater than centre bore, described blind hole is concentric with centre bore, at the inner stepped hole that forms of flywheel centre bore, be provided with the expansion set that size is suitable in the cannelure that described stepped hole and motor shaft form.
2. according to the motor flywheels fixed mechanism of claim 1, it is characterized in that: the specification of described expansion set adopts JB/T7934-1999.
